LUBRICATOR.

SPECIFICATION forming part of Letters Patent No. 293,590, dated February 12, 1884.

Application led June 30, ISB. (No model.)`

and iigures of reference marked thereon,which 1 form a part of this specification.

My invention relates to improvements in that class of lubricators wherein the oil' is fed to the parts to be lubricated by overliowing the reservoir thereof by admitting therein water formed by condensation of steam; and itconsists .in the construction and combination and arrangement of the several parts, as will be hereinafter more fully described `and claimed. y

In the drawings, Figure l is a perspective view of my lubricator and a section of the steam-pipe. Figs. 2 and 3 are vertical sections of the lubricator, the reservoir being partially broken away; and Fig. 4 is a detail view of.

the dropper, as will be described.

Like letters designate like parts vthroughout the several views.

lThe cup Ais provided at its lower end with thepetcock A', for drawing oft' the water before refilling the cup, and at its upper end it has the neck or extension A2, through' which the vertical passage a is formed. This passage at its upper end is enlarged and threaded to receive the lower nipple of the sight-cylinder. The sight-cylinder B is constructed with open'- ings at both ends, which are covered byglass plates b, which'are suitably packed and secured in place by screw-rings b', as most clearly shown in Fig. 3. Nipples B' B2 are extended from, respectively, the upper and lower sides of the cylinder B, through which nipples are openings b2 b3, in line with the passage a in the oil-cup. These nipples B' B2 are threaded externally, in order to connect the cylinder with the condenser and reservoir-cup, as shown. The passage b2 through the nipple B is contracted at its lower end and threaded to receive the dropper G2, which turns through the said passage, and is provided with a drop ping-opening. This dropper is arranged directly over the passages b" a, and is provided at its upper end with the nick c, to permit the Asaid dropper to be turned up or down to vary the distance between it and the cup. It will be understood that, when so desired, the dropper could be cast integral with the sight-cylinder, but I prefer to make it as shown and before described, so that it may be adjusted to vary the distance the drop of water falls on the oil. By employing this dropper, and extending its lower end within the cylinder,'the quantity of water passing into the cup can be more readily determined than were the same allowed to trickle down the wall of the cylirrA der. Nipples B3 B4 are extended horizontally from the sides of the cylinder and midway the ends thereof. The supply-pipe C', provided with cap c', is screwed on the nipple B3, and the oil-feed pipe D is screwed on the nipple B4. This oil-feed pipe D furnishes a passage through which the oil flows to the lengine-cylinder. This pipe D is provided with a suitable valve, D', and is connected with the steampipe E ly means of the T E', as shown in Fig. l. The condensing-pipe F is connected with the steam-pipe E in the manner clearly shown in Fig.'1, and is provided at its lower end with the valve-chamber F', which is connected by threaded j oint with the nipple B'of the cylinder. Within the chamber, I arrange the valve-seat F2, which extends from side to side of the chamber, and is constructed with the vertical intermediate plate through which the opening f is formed, and with the inclined plates f' at its upper and lower ends. The lower plate f' is deflected or bent over to one side clear of the passage f 2, leading into nipple B', and forms a receptacle, f3, for the water, as the same is condensed under the pipe F. A bearing, G, is extended horizontally from the valvechamber in a line parallel with the sight-cylinder, and provided with suitable packing-box, G', as shown. The valve H is provided with stem h, having screw-thread h', turning in a threaded opening through the bearing G, and is provided on its outer end with hand-wheel h, so that the valve can be turned and adj usted to open, close the valve, or regulate the passa-ge of water, as may be desired'.

IOO

The oil and steam passages of mylubrica-tor are 'large and substantial. All small pipes, valves, &e., are dispensed with, and there is consequently little, ifany, chance for stoppage or getting out oforder. By arrangingthe sightchamber with transparent ends the passages of Water and oil may be seen from either side.

My lubricator, it will be seen, is simple in its construction, and can be manufactured at a small cost, and will be substantial and not likely to get out of order, andthe several parts are compaetly arranged, so as to take up but small space.

Having thus described my invention, what I claim, anddesire to secure by Letters Patent, is-

as described and shown, composed of the cup or reservoi r arranged at the lower end thereof, the sight-chamber mounted thereon, and the condenser arranged above the sight-cylinder, the said reservoir, sight-cylinder, and con denser being arranged in a line, one above the other, and provided with connecting passages or-openings, also arranged or formed in line with eachother, as and for the purposes specified.

2. The lubrieator, substantially as described and shown, consisting ofthe cup or reservoir A, the sight-cylinder mounted thereon, and closed at its ends by transparent plates, and communicating with the cup A through the passage b a, the horizontal pipe D, connecting l. An upward-feedlubrieator, substantially thesight-cylinder andthe steannpipe, the feedpipe C', opening into the cylinder at a point opposite the connecting-pipe D, the dropper (l, threaded as shown, and adjust-able into Athe cylinder 13 in line with the passage b a, and the condenser F, communicating with the droppcr C2, and provided with suitable valve, F', the suid condenser, dropper, and passage b c being arranged in line with each other and relatively to the oil-feed and connecting pipes C' D, all as and for the purposes specified.

3. In a lubricator, substantially as herein` before shown and described, the sight-chamber B, having its opposite ends or openings closed by transparent plates b, and provided withy upper and. lower nipples, B' B, and lateral nipples B B", in combination with reservoir A, screwed on lower nipple, B2, the condenserpipe F, screwed on upper nipple, B', and provided with suitable valve, F', the feed-pipe C' and connecting-pipe D, screwed, respectively, on the nipples B B", and the dropper C2, forming the connection between the condensingpipe and the sight-chamber B, and extended into the latter and adjustable vertically, in the manner as and for the purposes specified.

In testimony whereofl affix my signature in presence of two witnesses.
